Figure 3. Effect of the extent of surgical resection on survival. (A) Complete resection is a significant prognostic predictor of overall survival, as evaluated by log-rank analysis. (B) Complete resection is a significant prognostic indicator of survival from thymoma, as evaluated by log-rank analysis. Complete resection is the most important independent predictor of overall survival and the only independent predictor of thymoma-related survival, as analyzed by Cox regression.
